Windows 10: INACCESSIBLE BOOT DEVICE

Hello am Eman, I am facing a trouble from previous night and no body helping me I don't know what to do how I can get rid of it. Actually yesterday I was told by a lenovo Expert to download OneKey optimizer to Calibrate my battery as it's capacity reduced a lot. As per his instructions I downloaded and It needs a restart and I did it but there is the problem whenever am starting my laptop from that restart always there a BSOD comes and it shows the error code "INACCESSIBLE BOOT DEVICE" and after that "Preparing for automatic repair" showing but nothing going to happened. I trued all the methods I tried to 3 times force shut-down and turn on butbhere another problem is coming whenever I try to enter in Advanced Options then it says to Select an account I select my microsoft account which is on my lapi but again it recurries the password and whatever password I gave it my mail password or computer log in password it won't take it I even change my mail password too but nothing works. I remember same kind of issue I faced while installing and restarting of OneKey optimizer but then my friend is did something on the bios setup and magically the laptop turns on and I simply delete all the files of OneKey optimizer including drivers and i never faced that, but what we did in that time in bios set-up we can't remember. so if there a person who knows how to get rid of it please help me please I need your help please.

This is a Microsoft link on inaccessible boot device:
https://docs.microsoft.com/en-us/win...le-boot-device

It is an intermediate level link.
There are more advanced steps that can be ran once the partition structure is known.
There are steps for repair of the boot sector, operating system, etc.
Sometimes this bugcheck can be caused by windows updates.

A reset save files equivalent may be able to be performed.
Alternatively a clean install can be performed once important files are backed up.

I'm not sure if this is helpful, but maybe you can have a try. Windows operating system backups a working registry for recovery purpose. You can perform registry backup restoring to fix the inaccessible boot device error. The pre-condition is that you can access to the Advanced startup opotions of your PC. You'll need to use the command prompt.
Also, steps are a little bit complicated. However, if you follow the guide strictly, no mistake should be made. You can Google how to restore from Registry Backup, or refer to this article for help. Inaccessible Boot Device Lenovo.
